The correct option is B One million three hundred five thousand two hundred nine.

Let us first convert the given number in words into numerals as follows:

Thirteen lakh$=13,00,000$

Five thousand$=5,000$

Two hunderd$=200$

Therefore, the required number is $13,05,209$.

Now, to convert the number in International number system, we write the number as follows:

$1,000,000=$One million

$305,000=$Three hundred five thousand
